ATC executive general manager racing services, James Heddo, said the Golden Slipper remained the race that shaped Australian racing and breeding.

“The Longines Golden Slipper is the race every owner, trainer and jockey first dreams of winning and that dream begins again with these first nominations,” Heddo said.

“This year’s numbers remain very strong for the world’s richest race for two-year-olds run on Australia’s biggest day of Group One racing.”
